* Fine grained ingot (CT) produces properties similar to the above.
(2) Add one hour per inch of section thickness.

NOTE: Heat treatment (for pattern design) from as cast, not from solution annealed, shrink characteristics are 0.001 in./in. in all directions. Shrink characteristics for maximum properties from solution heat treat are 0.002 in./in. in all directions.
